Animal Characteristics:

Multicellular, Heterotrophic, Eukaryotic, no cell walls, typically reproduce sexually, capable of motion at some stage in their life.

We will survey the Kindom Animalia by looking at the 9 major phyla from the simplest animal phylum to the most complex animal phylum.

SYMMETRY

Symmetry-- Body Plan. How body parts are arranged. The balanced distribution of duplicate body parts or shapes.

3 types of symmetry are seen in animals.

1) Asymmetry--No Body Plan

Ex. Sponges

2) Radial Symmetry- Body parts arranged around a center point.

--Any cut through central point results in identical halves.--No head, front, back.--Oral surface and an Aboral surface.

Ex. Sea Anemone, Jellyfish, Starfish, Sea Urchin

3) Bilateral Symmetry- Arrangement of body parts along a central line or plane.

--Only one way to cut to get mirror image halves.--Use terms like: anterior, posterior, dorsal, ventral

Ex. Worms, lobster, whale, clams, human, squid

All bilaterally symmetric organisms have a dorsal, ventral, anterior, and posterior region.
